WILLIAM A. KENNEDY, OF KANSAS CITY, MISSOURI.

LISTER-CULTIVATOR.

To all whom it may concern:

Be it known that I, WVILLIAM A. KENNEDY, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Lister-Cultivators,of which the following is a specification.

This invention relates to lister cultivators, and more especially tothat type having ground wheels to run in the furrowsand disks to turnsoil into the furrows, and my object is to produce a machine of thischaracter which operates efliciently and reliably and which can bemanufactured at a comparatively low cost.

With this object in view the invention consists in certain novel andpeculiar features of construction and organization as hereinafterdescribed and claimed; and in order that it may be fully understoodreference is to be had to the accompanying drawings, in which:

Figure 1, represents a side elevation of a two-row machine embodying theinvention. Fig. 2, is .a top plan view showing a single gang, and theseat-plank and lever broken away. Fi 3, is a vertical section taken onthe line II III of Fig. 2. Fig. 4, is an en larged horizontal sectiontaken through the ground wheel arch and showing certain parts connectedto the same. Fig. 5, is an enlarged section taken on the line VV ofFig. 1. Fig. 6, is a vertical longitudinal section of one end of theaxle and the parts carried thereby, looking forward.

In said drawings 1 indicates a frame or tongue, 2 the usual double-tree,and 3 the seat-plank for connecting the gangs of a double row machine,said seat-plank being supported on the parallel rods 4 of each gang,secured at their front ends to the cross-bar 5 fastened by bolts 6 tothe tongue, and at their rear ends to cross-bar 7, fastened by bolts 8to the block 9 bolted on the tongue.

10 is a toothed sector secured to block 9, and pivoted to said sector at11 and extending u ward therefrom and inwardly towards the rivers seat(not shown) on the seat plank, is a lever 12 provided with latchmechanism 13 for engagement with the sector.

14' is a rod ivotally connecting the lever to the inverte U-shapedrock-bar 15 pivoted as at 16 to the tongue.

17 is an inverted U-bolt secured to the tongue and forming a journal foran arched Specification of Letters Patent.

axle 18, provided at its lower ends with outwardly projecting arms 19 onwhich are journaled ground wheels 20, hub portions 21 of the groundwheels projecting inwardly and engaging grooves 22 in the brackets 23our naled on arms 19 and having bifurcations 24 receiving thebody-portion of the arch, the brackets being secured to the arch byspringcotters 25.

26 and 27 are lugs projecting forward and rearward respectively frombrackets 23, and 28 is a U-shaped link ivotally connecting lug 26 withthe lower end of rock frame 15.

29 are collars adjustable on arms 19, and secured rigidly on said armsbetween said collars by U-bolts 30, are rearwardly rojecting arms 31,the rear ends of said arms eing longitudinally channeled in their lowersides, as indicated in Fig. 5.

33 are eye-bolts extending up through arms 31 and forming pivots forlinks 34 surmounting arms 31, nuts 35 engaging said bolts to retain thelinks in position.

36 indicates an arched brace journaled in bolt 17 and having its bridgeportion paralleling the corresponding portion of arch 18 and having itsarm diverging downward with re- 'spect to arch 18 and pivoted at itslower end to links 34; said links being adapted to assume varying angleswith relation to the tongue when the arms 31 are adjusted outward orinward on arms 19 to permit the ground wheels to be moved a greaterdistance apart or closer together, and also for inward or outwardadjustment of the cultivating devices.

37 indicates cylindrical arms fitting in the hollowed or channeled sidesof arms 31 and provided with longitudinal ribs 38 to engage one oranother of the longitudinal grooves 39 in the rear ends of said arms 31;said arms 37 also extending through the eye-bolts 33 to be clamped bythe latter at the desired point of adjustment in arms 31, eitherlongitudinal or rotatable, the engagement of the ribs 38 with grooves 39guarding against accidental turning movement of the arms 37. Pivoted asat 40 to the ends of arms 37 are shafts 41, the usual means (not shown)being employed to secure said shafts at the desired angle with respectto said arms, and journaled on said shafts are disks, preferably seriesof disks 42, 43 and 44 of diminishing diameter respectively.

45 indicates a fender arranged between the two series of disks andvertically below the tongue, the sides of the fender being connected attheir rear ends by a pair of bars 46 adjustably secured together. 47 arelinks pivotally connecting the front end of the fender to the rearwardlyprojecting lugs 27 of brackets 23, as shown at 48.

49 indicates a cable or chain secured at its lower end to cross-piece46, and at its upper end to the lever 12 and extending through anapertured guide-bar 50 projecting upwardly from block 9.

51 indicates a chain connecting bars 5 and 7, and equipped about mid-wayits length with a ring 52 engaging a rod 53 carried by and extendinglongitudinally of and below the seat-plank, and also extendinglongitudinally of and below the seat-plank are bars 54; said bars alsounderlying rods 4 to prevent either end of the seat-plank tilting upwardfrom any cause.

In practice the parts are arranged as shown in Fig. 1 when the machineis driven to or from a field, in which position it will be noticed thatthe weight of the machine is practically balanced on the ground wheelsand that, when the lever is thrown forward, it not only pushes theground wheels rearward and raises the disks but likewise elevates thefender and the brace 36. When the cultivating operation is to takeplace, the lever is thrown rearward, as indicated in Fig. 3, this actionthrough the connections described, causing the ground wheels 20 to rollforward and rock arch 18 and brace 36 until the disks come intoengagement with the ground, the fender at the same time assuming itsproper position upon the ground with relation to the plants (not shown).In the cultivating operation the arch 36 acts as a brace to hold thedisks firmly embedded at the required depth, and at the same time theconnection between the arch 36 and arms 31 permits of lateral adjustmentof the ground wheels and a variation of distance between the disks. Theend-wise movement of the seat-plank does not interfere with the oper-'ation of the machine and is limited by the bars 54, and the forward andback movement of the seat-plank is limited by the front and rearsections of chain 51, as will be readily understood. The cultivator canbe used as a single or double row, and will work equally as well for thesecond or third cultivation.

From the above description it will be apparent that I have produced acultivator embodying the features of advantage enumerated as desirable,and which obviously may be equipped with a single disk at each side inlieu of the series of disks and also with shovels if desired.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent, is

1. Alister cultivator comprising a tongue, an arched axle journaledthereon and equipped with ground wheels, laterally adjustable armsprojecting rearward from said axle, disks suitably journaled and movablewith said arms, an arched brace ournaled on the tongue and extendingdivergently downward with respect to the axle, and links pivotallyconnecting the arched brace and said arms; said links being pivoted formovement at right angles to the pivotal movement of the arched brace onthe tongue, to accommodate lateral adjustment of said arms toward orfrom each other.

2. Alister cultivator, comprising a tongue, an arched axle journaledthereon and equipped with ground wheels, arms projecting rearward fromthe axle, disks suitably journaled and movable with said arms, an archedbrace between the tongue and said arms and extending divergentlydownward with respect to the axle, a rock frame mounted on the tongueand linked to the axle, a lever linked to said frame, a toothed sector,and catch mechanism carried by the lever for engagement with the sector.

3. A lister cultivator, comprising a tongue, an arched axle journaledthereon and equipped with ground wheels, arms projecting rearward fromthe axle, disks suitably journaled andmovable with said arms, an archedbrace between the tongue and said arms and extending divergentlydownward with respect to the axle, a rock frame mounted on the tongueand linked to the axle, a lever linked to said frame, a toothed sector,catch mechanism carried by the lever for engagement with the sector, afender between the disks and linked to the axle, and a suitably guidedflexible connection between the lever and the rear end of the fender.
